The ph level of a solution measures how acidic or basic the solution is. values between 0   and 7   are considered acidic while values between 7   and 14   are considered basic. the ph is calculated by using the equation ph =−log⁡⁡[h3o+] . the notation ­ ­ ­ [h3o­­­+]   represents the concentration of hydronium ions, which is measured in units of moles per liter, m .    what is the ph level of a solution if [h3o+]=3.4×10−3m ?
